SHIP-REPAIRING APPLIANCE.

Specification of Letters Patent.

Application filed March 19, 1914. Serial No. 825,858.

To all whom it may concern Be it known that I, TOMASZ CZERNIAWSKI, a subject of the Emperor of Austria-Hungary, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Ship- Repairing Appliances, of which the following is a specification.

This invention relates tocertain new and useful improvements in ship repairing appliances.

The primary object of the invention is to provide means carried by a ship and substantially below the water line thereof and positionable for immediate use for covering a hole or opening formed in the hull of the ship by an accident or a collision.

A further object is to provide a compact hole-repairing curtain at a point adjacent the keel of the ship and readily shiftable for inclosing substantially the entire exterior surface of the hull as an advantageous protector against the entrance of water through the hole.

It is further devised to provide a hull inclosing curtain positioned fully protected upon the keel portion of the ship and readily manipulated from the deck of the latter to be extended as a covering over substantially the entire hull surface and automatically guided during the unrolling operation.

With these general objects in view and others that will appear as the nature of the invention is better understood, the same con sists in the novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the appended claims.

In the drawings forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views: Figure 1 is a side elevation of a ship showing my improved device upon one side thereof in its closed position. Fig. 2 is a vertical transverse sectional view thereof substantially upon line 22 of Fig. 1, with the device positioned upon both sides of the ship, and Fig. 3 is a horizontal longitudinal sectional view upon line 3--3 of Fig. 2 with the curtains unrolled.

Referring more in detail to the drawings, the ship 10 is illustrated as provided upon both sides of the keel 11 thereof with elongated casings 12 having tapered ends 13 for giving the same less resistance to the water during the passage of the ship therethrough.

12 similar to the usual form of windowshade, the same being secured to and rolled upon the central axle or roller 16. The roller of each curtain is trunnioned in any desired manner within its respective casing, as by means ofbearing brackets 17 positioned within and adjacent the opposite ends of the caslng while each casing is provided with a top opening or slot 18 and through which the curtain 15 extends and is adapted to be unfurled by means of cables 19 secured adjacent the ends of the curtain by means of loops 20, while the other ends of said cables are attached for winding upon the drums 21 mounted upon the gunwale 22 of the ship.

The curtains may be provided with springs for normally retaining the same rolled upon the axles 16 although the same is not necessary to the perfect operation of the device. A dove-tailed tongue block 23 is secured to the inner face of each curtain 15 adjacent the opposite ends thereof and is slidably positioned within slidable guideways or strips 2 1 vertically secured in spaced relations upon the side of the hull and whereby it will be evident that the curtain will be guided thereby in its upward movement upon the outside of the hull.

From this description, the complete operation of the device will be apparent.

In the event of a collision which forms a hole or break in the hull, the winding drums or windlasses 21 may be operated by the crank handles 2:) thereof to unwind the curtain and manually draw the same up the side of the hull, substantially inclosing the hull and extending over the hole in the side thereof. The pressure of the water upon the outer side of the curtain forces the curtain firmly against the hull and closes the aperture therein against the entrance of 1 water from without. Such repairing of the hull. is deemed suilicient until the ship is enabled to reach its destination for permanent repairs.

It is obvious that the present arrangement may be provided for only the main side portions of the hull or may be positioned sub- Patented June 9, 1914.

stantially entirely around. the'same and thescope of the present invention includes'such positioning of the present curtainstructure.

While the forms of the invention herein shown and described are what are believed to be preferable embodiments thereof, itis nevertheless to be understood that various forms and modifications thereof may be had without departing from the spirit and scope of the invention as claimed.

' 'l/Vhat I claim as new is ,1. A device of'the class described, com,- prising in combination with a ship-hull, a rolled curtain trunnioned upon the keel thereof, "means positioned; upon the deck of the ship adapted for unrolling saidcurtain vin contacting position with the hull,'and

guide means upon said hull for said curtain. U 2. A device ofthe class described, comprising tapered casings having top slots therein and oppositely positioned longitudinally upon the keel of the ship, axles trunnioned Within said casings, curtains'mounted upon said axles and projecting through said slots, hoisting means secured to said curtains and mounted upon the deck of the ship,

and guides for said curtains extending upwardly upon the ships hulL, 7

3. A device of the class described, comprising tapered casings having top slots upon said axles and projecting through said slots, winding drums'positioned upon the I deck ofthe ship, hoistingcables upon said drums havingfltheir free ends secured to said curtains, slotted Ways upwardly-extendingupon the sides of the ship hull, and blocks carried by. said curtains and slidably positioned Within the slots of said ways.

In testimony whereof I afiiX my signature inpresence of two witnesses. a w
